HENRY G. THOMPSON, OF CLEVELAND, OHIO.

PRESSED METAL WHEEL.

Application filed may 2, 1921.

To all whom it may concern:

Be it known that I, HENRY G. THOMPSON, a citizen of the United States,residingat Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented a certain new and useful Improvement in Pressed Metal Wheels,of which the following is a full, clear, and-exact description.

This invention relates to pressed metal wheels and more rticularly toaconstruction which is particularly adapted where the load to be carriedby the wheels is a light load, as for instance, toys, although the usepiffiihe Wheel is not limited to this particular One of the objects ofthe invention is to produce a pressed metal wheel from sheet metal by astamping process, which may be easily formed and easily assembled, butat the same time making quite a rigid structure which gives the wheelsuflicient strength for use with light loads.

Reference should be had to the accompanying drawings forming a part ofthis specification in which Fig. 1 is a side elevation of a wheelj Fig.2 is a section upon the line 2-2 of Fig. 1; Fig. 3 is an elevation ofone of the stampings which is used in producing the wheel; Fig. 4 is asection upon the line 4 4 showing portions of the two stampings used;Fig. 5 is an elevation of a modified construction and Fig. 6 is asection upon the line 6-6 of Fig. 5'.

Referring to the drawings, which-show the herein described invention, 1indicates a' stamped' metal disc which is adapted to cooperate with asecond stamped metal disc which is indicated at 2. The disc 1 is formedfrom a blank piece of metal and provides a rim portion 1 and a centralhub portion 1 and radiating spokes 1. Thisblank forms in effect half ofa wheel and the spokes are formed half round with intermediate spacesformed by severing the metal. The hub is provided by forming anoutwardly flaring" portion as indicated in Fig. 2 and is providedwith aninwardly extending flange 1 The rim portion of the wheel is formed witha rounding portion and also with a straight flange 1 which extendsoutwardly from the rounded portion 1.

a The member 2 of the wheel is formed with central spoke portions 2which are formed precisely the same as the spoke portions 1 and havingintermediate portions-between the spokes cut away. The hub portion 2Serial No. 466,131.

is pressed outwardly the same as the portion 1 and the hub portion hasan outwardly extending flange 2 which is similar to the inwardlyextending flange 1, except in the present instance the flange 1 iscupeshaped as clearly indicated in Fig. 2. The rim portion of the wheelis indicated at 2 and it is formed as a half round ortion bein ofsubstantially the same ra ius as the alf round portion 1. v

The two halves of the wheel land 2 are assembled by bringing the spokesso that they superimpose and the edge of the half round portion extendswithin the flange 1 as indicated in Fig. 4.

When the two halves are thus assembled, the flange 1 is by a pressingoperation bent into contact with the outer surface of the half roundportion 2 as indicated in Fig. 2 and additionally an eyelet 3 isinserted through the central openings of the hubs so that the flange 3*comes against the flange 1 and when in this position the eyelet isexpanded at the other end so that the expanded portion 3 fits againstthe flange 2.

The member has been described as an eyelet, because in small sizedwheels, such for instance as those having a diameter of approximately 2inches or thereabouts, an ordinary copper eyelet, such as is well knownon the market, may be used.v However, it will be understood that no*limitation is intended to this precise eyelet as any cylindrical shapedmember which may be pressed into contact with the hubs 1" and 2 may beused with good results. The member- 3 should of course be hollow so asto permit the wheel to be mounted upon the axle of the toy or vehicle inconnection with which it is to be used. I 0 v The construction which hasjust been de- ICE.

scribed is exceedingly simple and one which are in contact enables thestructure to becompleted by folding the straight flange 1 around thehalf round portion '25, thus'not only completing the rim portion of thewheel, but effectively joining the tWo halves of the Wheel at the rimportion,

In Figs. and 6 there is shown a modified form of construction, which,however, is only modified to the extent that the spokes 5 and theintermediate portions 6 of the wheel are maintained in unitary form, thespokes being merely formed by throwing a bead into the sheet metal whichof course stiflens the sheet metal perceptibly and gives the impressionof spokes.

The formation of the rim portion and the formation of the hub portion ofthe wheel as Well as the manner of assemblying the two half portions ofthe wheel and securing them together are the same as that which haspreviously been described.

Having described my invention, 1 claim:

1. A. sheet metal wheel formed off-two cooperating annular parts each ofsaid parts being formed with a central opening and a hub portionsurrounding the-same, each of said parts at the periphery being formedwith a substantial half round portion which are oppositely disposed whenthe parts are assembled, the edges. of one of the half round portionsextending over and beyond the edge of the other of saidportions and thehalf round portion which conforming to of said parts having interitoverlies, each mediate portions between the hub and the half roundportions "which lie in contact with each other, and a sleevemember'which wheel formed. of two co-' portions extending over andbeyond the other of said porti s and conedge of the the half roundportion which it forming to overlies, each of said parts being formed'with half round spokes which extend between the hub po'rtion andthe halfround portion'the edges of said spokes on the opposite wheel partsengaging, and a sleeve member extending between the hub portions of thewheel parts and connecting and holding them together.

In testimony whereof, I hereunto afiix my HENRY e. THOMPSON.
